Establishing Rapid Production System of Ortho Image Based on Aerial Camera with High-Precision POS System

摘要

As a new photogrammetry sensor, ADS40 still has no large-scale applications in our country. The low automatic degree and security classification are the main problems when handling data on the local coordinate system in the current production process. The automatic post-process method is put forward, which can remarkably simplify the data process flow, improve the data production efficiency and enhance the data security. Direct project parameter conversion instead of seven-parameter conversion is adopted in horizontal direction. A grid model is adopted to simulate geoid refinement and the strict conversion relationship is created in vertical direction.
